I agree, I always liked him at LSU, he hasn't converted that success to the NFL, but I think this is the year he either makes it or finds a new home.
His first year he seemed to do fine from the slot, but last year he seemed to drop a lot of balls thrown to him. I don't know whether it was his hands, or the fact that he wasn't prepared for a ball coming his way, but he did seem to look like he was fighting it by mid season.
See how he does in the pre-season, if he has made positive strides, and clicks with JP, keep him. If he is still struggling in the pre-season, and we don't see any major chemistry with JP, let him go, pick up a decent veteran.
